Oxalic acid is used to remove dark stains from wood. Proprietary wood stain removers often contain it. But presumably since yours is real wood it will have a coat of varnish which would require gentle sanding away in the localised area before treating the stain.Hi, The stains are black spots probably caused by damp, and I don't know what a photo veneer is, but I have a hobby van and it looks and feels like wood, but I'm prepared to be proven wrong
